@JeremyECrawford Can a wiz target empty air with fireball or does it need to hit something solid to detonate? Are air bursts legal?

Fireball requires you to choose its point of origin. Its text doesn't require that point to be on an object. A point in space is fine. #DnD https://t.co/g4piX26DlV

@SwampRobHow precisely can a wizard dictate that? Can he choose to cast it at a point exactly 23.5 feet away? As precisely as the DM allows.
